摘要 目的探讨乳头腺瘤的临床病理学特征、诊断及鉴别诊断。方法收集6例乳头腺瘤的临床资料,采用HE及免疫组化EnVision两步法染色,分析其临床病理学特征,并复习相关文献。结果6例患者均为女性,年龄20~44岁,平均32岁。临床主要表现为乳头糜烂、结痂及结节形成。镜下见乳腺导管上皮增生,呈实性、筛状或乳头状排列,或呈腺病表现,部分区域可见假浸润现象,伴大汗腺化生、坏死及角质囊肿等改变。免疫表型:6例肿瘤细胞ER呈不均匀阳性,CK(AE1/AE3)、CK5/6、CK7均呈阳性,SMA、p63、Calponin均呈肌上皮阳性,HER-2、p53均呈阴性,Ki-67增殖指数为5%。结论乳头腺瘤是发生于乳头的罕见良性肿瘤,易误诊为乳头Paget病及浸润性乳腺癌,依靠病理检查可明确诊断。
